| Title | This proposed work item is to define horizontal requirements for circularity related aspects of built environment digital passports.
The scope is to include the compulsory items: scope, normative references and terms and definitions. For the later, refer to and augment the anticipated standard from SC-1, WG-1: Framework, Principles and Definitions.
The PWI is to define and document the interrelationships and the dynamic changing of state over time of products in a built environment project, in order to promote a circular use of resources. The scope is to address issues of implementation and flow of the coming digital construction product passports once they are incorporated into a project, and to include the following scope:
Documentation of products in a project specific instance: The standard should address how products with product level documentation are integrated into built environment projects. It addresses information such as the type of products, their integration into construction components, itemization and tagging of groupings of products, quantities used, geographical location within the project, and assessment of their ease of accessibility and ease of demountability.
Data structures: The standard should define data structures that articulate the relationships between different products integrated into a construction project. This includes information on how products are interconnected within the building's design and construction, facilitating better understanding of material flows and dependencies. In addition, the integration of data from pre-demolition audits should be addressed.
Relation of project-integrated products to digital models (BIM): The standard should address how the information contained in the product level documentation passport is integrated into digital models, such as Building Information Modeling (BIM) and facility management models. This ensures alignment between physical construction elements and their digital representations (digital twins), enabling effective management of building information throughout its lifecycle.
Revisions to product level passports during project’s use-phase: The standard outlines procedures for revising product passports to reflect any changes made to products during the project’s use phase. This includes recording repairs, refurbishments, or replacements of products, ensuring that the passport remains accurate and up-to-date over time.
Product passport integration with Levels: The standard defines how product passports inventories are aligned with LEVELS’ Bill of Quantities (BoQ), which requires a structured list of materials and components included in the built environment project for life cycle assessment purposes.
Whole project tally for reporting in EU Taxonomy: The standard should facilitate the calculation of whole project tallies for reporting purposes, including compliance with the EU Taxonomy’s circularity criteria for both new construction and renovation projects. This enables stakeholders to assess the overall sustainability and circularity performance of the building project and track progress towards meeting regulatory requirements and sustainability targets.
Overall, the proposed standard for defining circularity aspects of built environment passports should address various aspects of documentation, data structures, integration with digital models, revisions during use, integration with Levels BoQ, reporting requirements and define the digital format. The proposed standard ensures comprehensive, standardized and dynamic documentation of construction materials and components when integrated into a built environment project, promoting transparency,
traceability, and resource recovery throughout the project’s lifecycle. In alignment with the EC Renovation Wave, this repository of information on a project’s resources should be digitally accessible in the form of a project log-books. |
